XML CDATA编码

不使用 InnerText :使用 XmlDocument.CreateCDataSection :

using System;
using System.Xml;

public class Test
{
    static void Main()
    {
        XmlDocument doc = new XmlDocument();
        XmlElement root = doc.CreateElement("root");
        XmlElement email = doc.CreateElement("email");
        XmlNode cdata = doc.CreateCDataSection("test@test.com");

        doc.AppendChild(root);
        root.AppendChild(email);
        email.AppendChild(cdata);

        Console.WriteLine(doc.InnerXml);
    }
}

随着 XmlDocument :

    XmlDocument doc = new XmlDocument();
    XmlElement email = (XmlElement)doc.AppendChild(doc.CreateElement("email"));
    email.AppendChild(doc.CreateCDataSection("test@test.com"));
    string xml = doc.OuterXml;

或与 XElement :

    XElement email = new XElement("email", new XCData("test@test.com"));
    string xml = email.ToString();
